MongoDB | CRUD Overview in MongoDB

In this video we are discussing crude overview

Now what is crude? So crude is nothing but in MongoDB the basic operations are create, read, update and delete

And these are known as the crude operations. So C stands for create, R stands for read, U stands for update and D stands for delete

So create, read, update and delete. So these are the very fundamental operations on MongoDB

Create operation. So, create or insert operations are used to add new documents into the collections

We know that MongoDB is a document-oriented database. So, under the collections, it will be having multiple documents

So create or insert operations are used to add new documents to the collections

If the collection does not pre then the collection will get created one is the read operation so this operation reads the documents from the collections we know that the collections will be having multiple documents and this read operation will read from the

documents this operation is used to take output of a query next we're having the

third operation that is the update operation it is used to modify existing

documents. So, documents will have the key value pairs. So, if you want to update, then this

particular operation will be executed on the documents. To change or update something in the

documents, we need to use this very operation. The last operation is our delete operation

to erase the documents from the collections, we have to use this respective delete operation

From the very name, it is quite obvious that we are going to delete our documents from the

collections. So, this is the crude operations and we'll be going for more details about them in the next

successive videos. Thanks for watching this
